The flag of the Philippine Navy has a navy blue field defaced with the seal
of the Philippine Navy: a navy blue roundel with an anchor in in purple,
superimposed over which is the traditional Philippine sea lion in Or; the
roundel surrounded by two stylized naval cables in Or, containing a white border
on which is written Hukbong Dagat Pilipinas (Naval Forces Philippines) with two
stars.Manuel L. Quezon III, 8 March 2002

Rectangular swallow-tailed pennant, blue over red, with white field at hoist
containing three yellow five-pointed stars. As the jack is from 1955, this may
well be the same for the masthead pennant.
